Ingredients:

  • 115g unsalted butter, melted and cooled
  • 150g brown sugar, packed
  • 2 large eggs, room temperature
  • 5ml vanilla extract
  • 60g sour cream
  • 340g mashed overripe bananas
  • 250g all-purpose flour
  • 5g baking soda
  • 3g salt
  • 1g ground cinnamon
  • 0.5g ground nutmeg
  • 85g walnuts, chopped and lightly toasted
  • 85g semi-sweet chocolate chips

Instructions:

  1. Preheat oven to 325°F (165°C). Grease a 9x5 inch loaf pan and line the bottom with parchment paper.
  2. In a large bowl, whisk together the melted butter and brown sugar until smooth.
  3. Add eggs one at a time, whisking well after each, then stir in the vanilla extract and sour cream.
  4. Stir in the mashed bananas until just combined.
  5. Sift the flour, baking soda, salt, cinnamon, and nutmeg directly into the wet ingredients.
  6. Using a silicone spatula, gently fold the dry ingredients into the wet. Stop the moment you see no more streaks of flour.
  7. Fold in the toasted walnuts and chocolate chips using three or four broad strokes.
  8. Pour the batter into the prepared pan and smooth the top.
  9. Bake for 55-65 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
  10. Let the bread rest in the pan for 10 minutes before transferring it to a wire rack to cool.
